G. L.. CURLE WASTE METAL GATCHER FOR TYPE CASTING MACHINES Filed May 12,1941 2 Sheets-Sheet 2 d( um@ Patented Jan. 13, 1942 WASTE METAL CATCHERFOR TYPE CASTING MACHINES- l2 Ciaims.

My present invention relates to improvements in Waste metal catchers foruse in connection with type casting machines. While this invention isintended for general use, it is especially Well adapted for use inconnection with Waste metal spouting systems of the type disclosed andbroadly claimed in my two United States Letters Patents No. 1,875,565issued September 6, 1932, and No. 2,186,801 issued January 9, 1940.

The object of these' spouting systems is to receive and 'collect wastemetal cut from type slugs or bars by the back knife, waste metal spillfrom the mold wheel, shavings removed from type slugs bythe knife wiperand waste metal and dust from a type slug sawing attachment, providedthe type casting machine is equipped with the same.

These catchers are provided and arranged to receive Waste metaldischarged from spouting systems at the terminals thereof and to receiverejected type slugs thrown by .hand by the operator of the machine.

More specifically stated, this invention is in the nature of animprovement or a refinement on the waste metal catchers shown in theabove identified patents wherein the waste metal catchers are removablymoimted on under-slung brackets detachably secured to the machines.These brackets are objectionable for the reason that they materiallyinterfere with the care of the machine and the floor thereunder, as Wellas certain adjustments of the machine that have to be made from time totime, and said brackets often have to be removed from the machine inorder to make the required adjustments.

One of the objects of this invention is to removably suspend thereceptacle of the waste metal catcherfrom an overhead support or cover,whereby when said receptacle is removed therefrom, the space below saidsupport or cover is unobstructed.

Another object -of this invention is to provide means whereby thereceptacle of a Waste metal catcher will freely slide from an overheadsupport or cover when removing said receptacle therefrom to empty theload of waste metal therein.

kA further object of the invention is to provide an overhead support orcover for the receptacle of a waste met-al catcher that will directJ`Waste metal from a spouting system or thrown by hand without 'spill orover-shot.

Still another'object of this invention is to provide an overhead supportor cover for the receptacle of a waste metal catcher having a novelapron for directing Waste metal from a slug sawing attachment into thereceptacle.

These and other objects of the invention will be apparent from thefollowing description and accompanying drawings.

To the above end, generally stated, the invention consists of the noveldevices and combinations of devices hereinafter described and defined inthe claims.

In the accompanying drawings, which illus; trate the invention, likecharacters indicate like parts throughout the several views.

Oi" the parts of the type casting machinefragmentarily illustrated forthe purpose of showing the invention in working position, it isimportant to .note the central supporting pedestal l0, the

.horizontal left-.hand member or angle bar H of the main frame having onits front end a bearing t2, the upright standard I3 on the member I lthat forms a part of the main frame, the transverse shaft lll journaledat one end in the bearing l2, the left-hand leg l5 -of the melting pot,not shown, pivoted on the shaft I4, the left-hand leg l of the viseframe, not shown, pivoted on the shaft ifi, the lefthand justificationlever I'I and its rod. i8 and operatingv spring lil and certain ,partsof the quading and centering mechanism indicated as an entirety by thenumeral 2D.

Mounted on the type casting machine and fraginentarily illustrated is aspouting system, and of the parts thereof shown it is important to notethe discharge end portion of a spout 2l that collects andccnveys wastemetal taken from slugs by the back knife, and the delivery end portionof a spout 22 that collects and conveys waste metal spill from the moldwheel and shavings removed by the knife wiper. rI'he spout 2l isprovided with an auxiliary extension 23 having a depending lip 24. Thenumeral 25 indicates the discharge spout, fragmentarily illustrated, ofa slug. sawing attachment, not shown. The discharge spout 25 extendstransversely in front of the leg l and is secured thereto.

Referring now in detail to the improved metal catcher, the numeral 26indicates a scoop-like receptacle having an open top. In the frontmember of the receptacle 2G is a hand hole 21 and an intermediatetransverse handle 23 is secured at its ends to the sides of saidreceptacle at the top thereof. The upper edge portions of the sidemembers of the receptacle 26 are turned outwardly into horizontalpositions to aord at each side of the receptacle 26 a longitudinalflange or rail 29.

The receptacle 23 is removably suspended from the type casting machineby means of an overhead support or cover 30. This cover 39 is located onthe left-hand side of the type casting machine and extends from thefront toward the rear thereof. The major portion of the cover 3B isoutwardly of and below the frame member l l. The left-hand side memberof the cover 30, at its rear end portion and top thereof, is inset at 3Eto receive the front end portion of the frame l l and its bearing I2,see Fig. 6. The cover 30 is detachably secured to the frame member ll bybolts 32, and its top member is downwardly and outwardly inclined fromthe upper face of said member and ailords clearance for the left-handjustication lever l1 which works thereabove.

The receptacle 26 is removably supported from the cover 30 by means ofrollers 33 on which the tracks 29 rest. These rollers 33 are journaledon the side members of the cover 30 at the inner faces thereof inlongitudinally spaced arrangement. The rollers 33' are located at thelower edge portions of the side members of the cover 30 and the frontmember of said cover, at its lower edge portion, is cut away at 34 topermit the receptacle to enter the cover 30 by sliding its rails 29 onthe rollers 33, see Fig. 6.

On the front member of the cover 3i] are outwardly extended iianges 35arranged to engage the front ends of the side members of the cover 3) asstops to limit the movement of the receptacle 26 under said cover andposition its front member in the plane of the front member of the cover30.

On the right-hand side of the cover 30 at the front thereof is a hopper36. The auxiliary spout 23 and its lip 24 are arranged to dischargewaste metal received from the spout 2| into the hopper 36 `at the rearend thereof and the spout 22 is also arranged to discharge waste metalinto the hopper 36 at the rear end thereof.

It is well known that the legs o the vise frame, which are pivoted onthe shaft I4, swing forwardly when said frame is opened and hence thedischarge spout 25 of the slug-sawing attachment which is secured to thevise frame leg IB moves therewith. In View of this movement of the spout25 relative to the hopper 35, said spout cannot be arranged to extendover said hopper and discharge waste metal directly there- To carrywaste metal from the spout 25 and discharge the same into the hopper 35,I provide a novel apron 31. This apron 31 is connected at its lower endby a hinge 38 to the upper edge of the right-hand side of the hopper 35.Said apron 31 is upwardly and outwardly inclined away from the wastemetal catcher and bears its upper end against the leg l5 and holds saidapron under the spout 25. In the upper end portion of the apron 31 is anintermediate cam surface 39 that normally extends in front of the legsI6. Vvhen the vise frame is opened, its leg I6 engages the cam surface39 and moves the apron out of the path of movement of said leg. Gravityholds the apron 31 against the leg I6 and returns said apron tooperative position when the vise frame is closed. On the front edge ofthe apron 31 is a perpendicular flange 40 that extends into the hopper35 and overlaps the front, member thereof.

Waste metal discharged into the hopper 36 from the spouts 2| and 23, 22and 25 is precipitated through said hopper and the cover 30 and into thereceptacle 26.

The left-side member of the hopper 36 is extended above the front memberof said hopper to aiToi'd a deilecting ilange 4I for interceptingdiscarded slugs thrown by the operator over the hopper and directing thesame therein.

By reference to Fig. 1 it will be noted that the quading and centeringmechanism 20 is substantially entirely rearwardly of the receptacle 26and the cover 30 and the major portion thereof is below said cover.

When the receptacle 23 is removed from the cover 30, free access may behad to the quading and centering mechanism 2U and other parts of themachine normally covered 01 obstructed by said receptacle. The entirespace between the cover 30 and the iloor at, when the receptacle 25 isremoved, is unobstructed.

As the improved waste metal catcher is substantially entirely to theleft of the type casting machine, it is not in the way of the operatorof the machine or does not interfere with access to the machine from thefront thereof.

From what has been said, it will be understood that the waste metalcatcher described is capable of modifications as to details ofconstruction and arrangement within the scope of the invention hereindisclosed and claimed.
